As always, it's important to note that these PS3 Debug / TEST updates will currently NOT install on a retail PS3, and so it is intended for examination and comparison purposes only unless you own a Dev unit.

For those curious, running this updater on a retail PS3 will not damage it, however, it will give the following error before the installation completes: The data type is not supported. (8002F029)

3.72 mixing the firmware

As I started getting an idea, I tried mixing in a little of the file between the 3.72 debug PATCH and the 3.72 OFW update (the full PUP). Now I found out that the patch has two more files that the actual update. File 10, and File 11. As I looked I came to conclusion that the vsh was within File 11.
